Assistant Management Accountant | Fast Growth Food Brand | London (Hybrid, 2 Days WFH)

Assistant Management Accountant | Fast Growth Food Brand | London (Hybrid, 2 Days WFH)The ClientA founder-led consumer manufacturing business that has built a serious following in a category long dominated by legacy brands. Growth has been quick across the UK and into international markets, and the business is now investing in the infrastructure to support the next phase, including a move from Xero to NetSuite and a wider rebuild of the finance systems stack. The London HQ is collaborative and hands-on, with a real focus on innovation and sustainability.The RoleSupporting the number one in finance, this is a role for someone who wants to build rather than maintain. You will support the month-end close, own the AP and AR ledgers (transactional processing sits with an outsourced provider, so your focus is oversight, accuracy, cash collection and resolving anything that gets stuck), and play a central part in the migration from Xero to NetSuite.Just as important is the appetite to improve how the function runs: automating manual work, using AI tools properly, and designing processes rather than inheriting them. The ambition is a best in class finance function, not one that simply keeps pace with the growth.This will suit either a credit control or AR specialist from an FMCG or consumer business who is ready for a broader step into management accounts, or a management accountant who is happy to keep their hands on the ledgers while building something better around them. Ideally you will have run AR or sales ledger for supermarket or major grocery customers, where the volume, the deductions and the payment terms are a different discipline entirely.Key ResponsibilitiesSupport the month-end close, including accruals, prepayments and monthly balance sheet reconciliationsOwn the AP and AR ledgers, managing the outsourced provider and holding them to accuracy and service standardsDrive cash collection and credit control across retail and trade customers, resolving disputes, deductions and short paymentsManage customer trading and EDI flows through TrueCommerce, keeping order, invoicing and remittance data cleanPlay a core role in the Xero to NetSuite migration: data cleansing, mapping, testing and process designPrepare and submit VAT returns, and maintain the fixed asset registerAssist in producing the management accounts and wider reporting packIdentify and build automation and AI assisted improvements across reporting, reconciliations and finance adminEssential Experience2+ years in a finance role within a consumer, FMCG or manufacturing businessStrong AP, AR and credit control experience, with a track record of getting cash inAR or sales ledger experience with supermarket or major grocery accounts is the strongest fit, including deductions, claims and retailer payment termsConfident with balance sheet reconciliations and the mechanics of month-endGenuinely strong with technology: quick to pick up new platforms, high level Excel, and already using AI tools to work faster and betterXero experienceA builder’s mindset; you want to fix and improve processes, not just run themDesirable ExperienceTrueCommerce, or a comparable EDI and order-to-cash platform such as SPS Commerce, Cin7 or BrightpearlExposure to an ERP implementation or migration, ideally NetSuiteExperience working alongside an outsourced or offshore finance providerExposure to management accounts production and reportingPackageSalary: £40,000 - £50,000Location: London HQ, two days working from homeIf you have any questions, please feel free to reach out to dan@harmonicfinance.comAt Harmonic, we are dedicated to fostering an inclusive and equitable workplace.
